Penmarch Place stands as one of Sioux Falls' most iconic and historically significant estates. This 1926 English-style residence, designed by Larson & McLaren, blends architectural grandeur, timeless craftsmanship, and serene privacy. A tree-lined road leads to the distinguished three-story home, where hallmark features include a circular drive with sundial, Flemish bond brickwork, sandstone detailing, copper accents, and a slate roof. The grounds offer a retreat-like experience with a pool, greenhouse, tennis/basketball court, and an additional garage with workshop. A solarium and a terrazzo dance floor on the rear patio provide spaces for both reflection and entertaining. Inside, you are greeted with imported Italian tile and original leaded windows. Reception rooms flow into the formal sitting room, library, solarium and formal dining room. With Portuguese cork-insulated walls and premium materials throughout, Penmarch Place offers enduring quality. This is more than a home--it's a rare opportunity to own a piece of Sioux Falls history.
